attributes in vec3b format. It looks like my compiler takes the wrong
overload and outputs integers instead of characters. The problem is
that vec3b is of type signed char and that is not the same as char (
see http://stackoverflow.com/questions/436513/char-signed-char-char-unsigned-char
) and visual studio 2013 will promote it to integer when choosing an
overload.
It looks like that the InputStream class already takes care of this
issue (if it didn't it would have read everything ok and I would have
not even stumbled upon this bug. :) )"
Updated lua plugin to use new osgDB::PropertyInterface to run methods.
Added addChild/removeChild() etc to Group.cpp, and addDrawable/removeDrawable() etc. to Geode.cpp serializers.
the wrappers it contains. The registration creates a prototype
object for all of the wrapped classes. For some of the higher-level
classes this can be a bit heavy.
I noticed a problem with a model which required a single class from
osgSim. When osgdb_serializers_osgsim.so was loaded it registered
wrappers and created prototype objects for all of the osgSim classes,
including osgSim::ScalarBar. The constructor for that class creates
several drawables, and loads arial.ttf using the freetype plugin. I
don't need that, and don't even ship the font or plugin with my
application, resulting in an unexplained warning message loading
the model.
I've modified the ObjectWrapper class to defer the prototype object
creation until if & when actually required."
// A custom class
namespace CustomDomain {
class MyGroup : public osg::Group
{
public:
META_Node( CustomDomain, MyGroup );
void setMyName( const std::string& n );
const std::string& getMyName() const;
void setMyID( int id );
int getMyID() const;
...
};
}
// The serialization wrapper using a custom domain name
REGISTER_CUSTOM_OBJECT_WRAPPER( MyDomain,
CustomDomain_MyGroup,
new CustomDomain::MyGroup,
CustomDomain::MyGroup,
"osg::Object osg::Node osg::Group CustomDomain::MyGroup" )
{
ADD_STRING_SERIALIZER( MyName, std::string() );
{
UPDATE_TO_VERSION_SCOPED( 1 ); // Updated for a new domain version
ADD_INT_SERIALIZER( MyID, 0 );
}
}
Save the class instance as follows:
osgDB::writeNodeFile( *myGroup, "serializer_test.osgt", new osgDB::Options("CustomDomains=MyDomain:1") );
The output file will include the domain version definition and all the class data, and can be read back. We can also force setting the domain version by the CustomDomains option while reading the saved files. If we save the class instance without any options, MyID will be ignored because the default domain version is 0.
This may help third-party libraries like osgEarth to maintain their own serializers without regarding to the OSG soversion changes.
Another feature added is a more robust binary format, which in fact adds a size-offset at each block's beginning. When there are problems or unsupported data types while reading, we can now directly jump to the block end indicated by the offset value. So a .osgb file will automatically ignore bad data and read remains as normal (at present it will fail at all). This feature will not break the backward compatibility, and can be disabled by setting "RobustBinaryFormat=false" while writing out.
Hope these changes can work smoothly with present and future community projects. Maybe we should also consider have an osgserializer example to test and demonstrate all things we can do now."
* ZeroConfDevice does now return FILE_NOT_HANDLED instead of FILE_NOT_FOUND
* present3D supports multiple devices per env-var P3D_DEVICE, separate multiple device with a space
I refactored parts the p3d-plugin, the curl-plugin and parts of Registry and ReaderWriter. Currently the p3d-plugin tries to open all remote files with the help of the curl-plugin.
I added a new method to Registry called getReaderWriterForProtocolAndExtension. which will return a ReaderWriter which is capable in handling the remote file for the given protocol and extension. If no readerwriter is found for the given extension, a list is built of all readerwriters supporting the given protocol and this list is checked for support of wildcards (extension = "*"). If anything matches it get returned.
I added this principle also to the Registry, so now it's possible to register a generic ReaderWriter which can handle all filetypes for a given protocol, similar what curl is doing. All you have to do is to load the plugin at startup. The curl-fallback is still in place.
With these changes it is now possible to reference a movie inside a presentation without a server-address, read the presentation (with curl) and stream the movie with the correct plugin (e.g. QTKit)

Added template readFile(..) function to make it more convinient to cast to a specific object type.
Added support for osgGA::Device to osgViewer.
Added sdl plugin to provides very basic joystick osgGA::Device integration.
macro, which could set version within brackets and reset it after
that. All related serializers are also modified so that the
backward-compatibility bug reported by Farshid can be fixed.

From Robert Osfield, removed the use of osg::Referenced and creating the proxy object on the heap.
